S T tires

Good, well sounding article full of a lack of real knowledge as to why a tire weighs what it does… tire weight alone isn’t a measure of quality…

Tire weight is part bulk, and part material selection and or processes used… to many variables to equate weight alone as evidence of quality…
Recipes of chemical or rubber compounding are one of the most closely guarded secrets of the tire industry…

cap ply’s might be made from single yarn or twisted cords… the single yarns can be cheaper, lighter, and thinner, but they can also be higher quality, improve heat dissipation, and reduce belt edge separation…

even tires from the same mfg. might have different LT model tires of different weights even in the same size and LR…

Quality can be made with lighter or heavier components, lighter or heavier compounds, and lighter or heavier cords or belts… one might be built with a heavier bead area and another with a heavier tread area…

For example from the 2012 Carlisle catalog to keep it apples to apples, that list the radial trail RH 205x75x14 LR C with a load rating of 1760 listed at 25.9 pounds…

Yet the Carlisle 215x75x14 LR C with a load rating of 1870 listed at 25.8 pounds… how is it that the tire with the higher load capacity has a lower weight…

The 225x75x15 LR C is bigger and weighs more than the 205x75x15 LR D but both have the same rated carrying capacity… citing and using weight as a leading indicator is misleading at best…

We outsiders don’t have enough information to know or say what the weight alone means…

All we can do is ask questions as to why is one tire heavier and what is the construction differences accounting for the differences…
